There should be an option of a quick matchup (like the one in arena) and one sending turns between friends.
It is a good idea in part that the pvp between the list of friends is sending turns but when you have your friend in a call or you want to play an intense game you will not be able to because it is sending turns, slower and less practical when facing friends and more when the game is available for pc since a lot of people use discord and stuff, so that style of game is very slow for a pvp between friends I come back and repeat.
We did receive a lot of players suggesting this mode. I have in fact already added this in my list to recommend to our devs to consider.
